LED Indicators

♦Power Lights when the DES-2212 Ethernet switch is powered on.

♦Console Lights when the DES-2212 console interface is in use.

♦MII Lights when the switch’s MII port is being used to connect to a transceiver. If there is an active connection on the MII port, then the Link/Act LED for port 2x will also light.

♦100M (Ports 1 through 4 ) Lights when the port is operating at 100Mbps. Ports 1 through 4 are NWay ports that can automatically detect whether 10BASE-T Ethernet or 100BASE-TX Fast Ethernet twisted-pair cable is connected.

♦Link/Act (Ports 1 through 12) Lights green when the port is connected to a powered-on Ethernet/Fast Ethernet station, and blinks off briefly when information is transmitted or received on the port.

♦FDX/Col (Ports 1 through 12) Lights green when the port is operating in full-duplex mode. Briefly blinks amber when a collision occurs on the Ethernet/Fast Ethernet segment.

♦System Load Shows a bar graph giving an indication of the network load, ranging from Low to High.
